DOOR-CHECK.

SPECIFICATION forming part 0f Letters Patent No. 469,968, dated March 1,1892. Application filed September 111891. Serial No. 404,404. (Nomodel.)

To all whom it may concern.-

Be it known that I, HENRY R. FRIsBIE, a citizen of the United States,and a resident of Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inCombined Door Checks and Holders, of which the fol-A lowing is aspecification. y

My invention relates to improvelnents in door checks and holders, itsobject being to check and break the force of a temporarilyopened doorwithout jar or shock; also, to provide means whereby t-he door, when sorequired, may be retained in an open position and readily disengagedtherefrom.

To this end my invention consists of two parts, one a `tapered metalthimble secured to the door, carrying a correspondingly-tapered rubberthimble whose contracted mouth is calculated to sustainand repel t-heshock of an opening door and react against a stud secured to thebase-board or to expand undera greater or more potent force and hold thedoor open.

The invention further consists in the construction and combination ofthe parts, as will be hereinafter fully set forth, and particularlypointed out in the claim.

In the accompanying-drawings, forming a part of this specification,Figure l is an end elevation of a broken section of a door andbase-board, also side elevation of the device attached thereto andacting, as represented,

in the capacity of'a check. Fig. 2 is a plan I, viewof the metal andrubber thimble. Fig.

3 is a sectional side elevation both of the metal and rubber thimblesthrough Y3 of Fig. 2 and a section ofthe stud through Y3 of Fig. l. Fig.4 is a front plan view of the metal thimble. Fig. 5 is a sectional sideelevation of said thimble through Y5 of Fig. 4. Fig. 6 is a sideelevation of the rubber tip or thimble; Fig. 7, a front plan view of thesame.

Its construction and operation are as follows: l represents the metalthi-mble; 2, the rubber tip or thimble placed within the one of metal;3, the door to which the metal thimble is secured by screws et. 5 is thecheck or holding stud, (as the case may be.) which is secured to thebase-board 6 by means of the central screw 7. S is an acorn-shaped headon the stud 5; .9,areduced portion or-neck of the stud with which thelip lO of the rubber thimble engages tohold the door open.

In the construction used heretofore it has 5 been difficult to employ anelastic device for the twofold purpose of the check and holder. If madesufficiently elastic to readily engage the stud, its holding power orgrip thereon is correspondingly reduced. Increasing its hold- 6c ingpower renders it liable to be detached from the door when disengagingthe stud therefrom.

In my device all the elastic properties of the rubber are brought outand utilized both as a check and holdback, while no amount of pull indisengaging the stud can displace it. The metal shell or thimblelformsasolid and firm support for the thin rubber thimble or holder 2,which is correspondingly tapered 7o and placed within said metalthimble. The contracted mouth 1l (see Figs. 2 and 7) is sufficientlyreduced toenable the head 8 of stud 5 (see Fig. l) to strike quite ablow and rebound therefrom when operating simply as a check; but whenrequired as a holdback sufficient power must be applied to force thehead 8 of the stud 5 into-the contracted mouth ll. As the rubber extendsbeyond the metal,

it will permit the mouth to expand sufficient 8o for this purpose,whereupon the rounded lip 10 will embrace the neck 12 of the stud.However rmly the lip 10 embraces the neck 9 the rubber cannot possiblybe pulled out is disengaged. Therefore the holding power may beincreased to any extent without such accident occurring. and the lip lOof the rubberthimble or holder 2 are so formed that the holding power isgreatlyimproved, while the shoulder 12 of the stud will prevent afurther entrance into the rubber thimble than is required to lock thedevice.

The neck 9 of the stud 'of the tapered metal thimble when the stud 85 Inattaching the device the thimble portion is first secured to the door,as shown. Then the stud, which carries its own screw, is placed againstthe base-board and on a line with the mouth of the portion on the door.A slight blow of the swinging door will cause the screw loo of the studto indent the base-board, at which point the stud will be secured. It'is quite the rot'ainingring, a semi cylindrical' lip formed at themouth of the thimblejand a stud with an entrance-edge and a shoulderadapted to pass into said thimble, substantially as and for the purposesdescribed.
